"We are pleased to have been able to amass so
much talent to create the celebration of musicals of the last decade that we
envisioned," Zadan and Meron said. "We are thrilled that so many talented
actors have agreed to bring our vision to life."

Earlier this month, the producers announced a planned
tribute recognizing the resurgence of musicals over the past decade with
performances highlighting "Chicago," "Dreamgirls" and "Les Misérables."
